Two vulnerabilities have been reported in Microsoft SharePoint Server, which can be exploited by malicious people to conduct clickjacking attacks and compromise a user's system.

1) An error can be exploited to cause a memory corruption.

2) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain unspecified actions by tricking a user into e.g. clicking a specially crafted link via clickjacking.
